Recycled regatta: world heritage site highlights plastic pollution crisis

1 year ago 123

Red Lion is the benignant of vessel you would not spot successful astir regattas. Its framework is made of bamboo, sourced from washed-up sportfishing equipment, and it uses 2 aged lipid drums for buoyancy.

Equally unusual is Rasta Rocket – made from aged integrative drain pipes, washed-up floats and sportfishing buoys.

These were 2 of the boats successful the inaugural Aldabra Regatta: an ironic effort to gully attraction to marine integrative contamination by racing boats made from marine debris.

Organised by the Seychelles Islands Foundation (SIF), a non-profit organisation that manages the Aldabra atoll, the lawsuit was a amusive but nevertheless last-ditch effort to combat backmost against the waves of integrative washing up connected this Unesco satellite practice site.

“A important information of 3 boats was made from marine litter associated with the sportfishing industry,” says Luke A’Bear, the subject coordinator for Aldabra and portion of a squad that lives astatine the isolated probe presumption each year.

The bamboo for Red Lion comes from fish-aggregating devices (FAD) – floating objects utilized to pull definite taxon of fish. They are often abandoned by the sportfishing vessel to prevention substance connected the travel backmost to shore. Huge chunks of bamboo, which tin instrumentality years to degrade, lavation up connected the beaches of Aldabra, blocking turtles from coming ashore to nest.

“Sadly, determination is nary effect and precise small inducement for FAD recovery,” says A’Bear, explaining however the determination to clasp the regatta felt similar a hopeless move. “It is going to instrumentality years for immoderate meaningful argumentation oregon authorities to travel into force.”

Another boat, Wakanda, built by Rickpert Woodcock, an electrician, and Alex Rose, who works successful logistics, with wood recovered from the beach, besides utilized washed-up floats for stability. A fourth, Floppy, was built by the manager of Aldabra island, Jude Brice, utilizing portion of a woody canoe that had washed ashore.

Island nations specified arsenic Seychelles carnivore the brunt of marine integrative contamination owed to the convergence of water currents. On Aldabra, researchers person observed the endemic elephantine tortoises eating plastic, seabirds entangled successful sportfishing lines and different examples of the havoc wreaked by marine litter connected some terrestrial and marine ecosystems.

“Just past week, we pulled retired a 200-metre longline with hooks and buoys that had got stuck connected the coral. We had to connect it to the vessel to beryllium capable to propulsion it off. It conscionable kept coming and coming,” says A’Bear. “And that’s conscionable 1 agelong line.”

“At our astir blimpish estimate, astir 68 tonnes of marine litter gets washed ashore annually,” says April Burt, an SIF probe subordinate based astatine Oxford University, who co-led the five-week Aldabra Clean-up Project (ACUP) successful 2019.

The corporate effort removed 25 tonnes of accumulated integrative litter from the atoll, astatine a outgo of $225,000 (£170,000), but that is simply a fraction of the 513 tonnes that ACUP researchers estimation inactive remains. “This fig [also] did not relationship for the caller litter arriving each year,” Burt adds.

An overwhelming 83% (by weight) of the marine debris remaining connected Aldabra is fishing-related gear, including buoys, nets, ropes and FADs.

The regatta was not a adjacent race: Floppy led passim the 1.5km course, yet winning by much than 300 metres, with Rasta Rocket edging Wakanda for 2nd place. The participants enjoyed themselves, but they are superior astir the challenges ahead.

“If you went to the beaches cleaned during the ACUP, you wouldn’t cognize that they person been cleaned,” says A’Bear. “Sometimes there’s 55kg of litter washed-up on a 50-metre agelong – successful 1 month. We’ve cleaned a formation a period before, and it’s similar you’ve done nothing. It’s depressing.”
